11.2 UNIDIRECTIONAL DIODE GATES

A unidirectional gate can transmit either positive or negative pulses (or signals) to the output. It means that this gate transmits pulses of only one polarity to the output. The signal to be transmitted to the output is the input signal. This input signal is transmitted to the output only when the control signal enables the gate circuit. Therefore, we discuss two types of unidirectional diode gates, namely, unidirectional diode gates that transmit positive pulses and unidirectional diode gates that transmit negative pulses.

11.2.1 Unidirectional Diode Gates to Transmit Positive Pulses

In order to transmit positive pulses, the unidirectional gate shown in Fig. 11.3 can be used. The gating signal is also known as ...
